Strong
60%+ sell-through with at least five relevant sold examples is a better candidate, assuming the profit math works.

How to use sell-through rate before buying eBay inventory.
A sold comp tells you an item can sell. Sell-through helps you decide whether it sells often enough compared with the number of active listings already competing for buyers.
The formula
Sold listings divided by active listings.
Use the same exact model, condition, and version when you compare. A broad brand search can make a weak item look better than it is.
Research
30% to 60% can still work if the buy price is low, condition is strong, shipping is easy, or the item is scarce locally.
Pass
Under 30%, or hundreds of active listings with few sold, usually means your cash may sit too long.
Example
If an exact calculator model has 12 sold listings and 15 active listings, the rough sell-through is 80%. That is worth researching further.
Bad example
If a charger has 4 sold listings and 90 active listings, the rough sell-through is 4%. The listing may sit unless your price is unusually low.
Do not stop there
Sell-through does not replace condition checks, shipping math, model verification, or fee estimates. It is one filter in the buy decision.
